Enum mz_storage_client::types::sources::Timeline

pub enum Timeline {
    EpochMilliseconds,
    External(String),
    User(String),
}

The meaning of the timestamp number produced by data sources. This type is not concerned with the source of the timestamp (like if the data came from a Debezium consistency topic or a CDCv2 stream), instead only what the timestamp number means.

Some variants here have attached data used to differentiate incomparable instantiations. These attached data types should be expanded in the future if we need to tell apart more kinds of sources.

Variants

EpochMilliseconds

EpochMilliseconds means the timestamp is the number of milliseconds since the Unix epoch.

External(String)

External means the timestamp comes from an external data source and we don’t know what the number means. The attached String is the source’s name, which will result in different sources being incomparable.

User(String)

User means the user has manually specified a timeline. The attached String is specified by the user, allowing them to decide sources that are joinable.

Trait Implementations

impl Arbitrary for Timeline

type Parameters = (<String as Arbitrary>::Parameters, <String as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Union<BoxedStrategy<Timeline>>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for Timeline

fn clone(&self) -> Timeline

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Timeline

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Timeline

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for Timeline

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Timeline

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Timeline

fn cmp(&self, other: &Timeline) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Timeline> for Timeline

fn eq(&self, other: &Timeline) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Timeline> for Timeline

fn partial_cmp(&self, other: &Timeline) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl RustType<ProtoTimeline> for Timeline

fn into_proto(&self) -> ProtoTimeline

Convert a Self into a Proto value.

fn from_proto(proto: ProtoTimeline) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

impl Serialize for Timeline

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToString for Timeline

fn to_string(&self) -> String
